Fuel Economy Potential of Diesel and Spark Ignition-Powered Vehicles in the 1980s 810514

The fuel economy potential of diesel and spark ignition engines is surveyed, recognizing that these engines will be the primary power sources for the passenger car and light truck fleets during the 1980s. These surveys treat 1979 production engines, and emphasis is given to state-of-the-art technologies; engine control strategies and special combustion system configurations are given special emphasis. Summaries are presented in terms of miles per gallon for engines installed in typical vehicles. The findings presented are an attempt to quantify fuel economy improvements that could be accomplished; they are not intended to predict any actual plans.
